Problems with the MPEG-4 format
Lower frame rate than expected. Check with the administrator that there is enough bandwidth available. Check also the settings
No MPEG-4 displayed in the
client.
No multicast MPEG-4 displayed
in the client.
Multicast MPEG-4 only accessi-
ble by local clients.
Poor rendering of MPEG-4
images.

To enable the updating of images in Microsoft Internet Explorer, set your Web browser to allow
ActiveX controls. Also, make sure that AXIS Media Control (AMC) component is installed on
your workstation.
Configure your AXIS 282/AXIS 282A to use a Java applet for updating the images under
Live View Config > Layout > Default Viewer for Internet Explorer. See the online help for more
information.
Adjust the X and/or Y offset, in the Video Source Settings. See the online help for information.
There is only limited space available for the upload of your own files. Try deleting one or more
existing files, to free up space
This can occur when trying to use a larger image buffer than is actually available. Try lowering
the frame rate or the upload period.
Configuring e.g. pre-buffers, motion detection, high resolution images, high frame rates, etc.,
will reduce the performance of the Video Server.
Slow performance may be caused by e.g. heavy network traffic, multiple users accessing the
unit, low performance clients, use of features such as Motion Detection, Event handling, Image
rotation.
In Display Properties, configure your display to show at least 65000 colors, i.e. at least 16-bit.
Using only 16 or 256 colors on your display will produce dithering artifacts in the image.
for bit rate control, in the Video & Image > Advanced > MPEG-4 settings. Using an inappro-
priate video object type can also affect the frame rate. See the online help for more informa-
tion.
Check in the AMC control panel applet (MPEG-4 tab) that video processing is not set to Decode
only I frames.
Lower the image resolution.
Reduce the number of applications running on the client computer.
Check that the correct network interface is selected in the AMC control panel applet (network
tab).
Check that the relevant MPEG-4 connection methods are enabled in the AMC control panel
applet (network tab).
In the AMC control applet, select the MPEG-4 tab and click the button Set to default MPEG-4
decoder.
Check with your network administrator that the multicast addresses used by the
AXIS 282/AXIS 282A are valid for your network.
Check with your network administrator to see if there is a firewall preventing viewing.
Check if your router supports multicasting, or if the router settings between the client and the
server need to be configured. The TTL (Time To Live) value may need to be increased.
Color depth set incorrectly on clients. Set to 16-bit or 32-bit color.
If text overlays are blurred, or if there are other rendering problems, you may need to enable
Advanced Video Rendering. This is done on the MPEG-4 tab in the AMC control panel applet.
Ensure that your graphics card is using the latest device driver. The latest drivers can usually be
downloaded from the manufacturer's web site.
Modify the settings for your graphics adapter. Please see the adapter's documentation for more
information.
